Can anyone identify this for me?

Found in a remote area on the high plains makes me think it is natural. But it looks man made to me. Too thick to be any glass that I am familiar with, not flat, and shaped like a rock. Air bubbles in it? Thanks in advance.

I found this, it kind of resembles it, mine turned out to be glass, probably the old coke bottles.

Thanks for the input. That's the same color. I can't tell from the photo but is your's somewhat clear with lots of little air bubbles in it?

If mine is old Coke bottle then it was melted down and re-hardened in a thick chunk. It's about 3/4" thick.

It has some bubbles and it's clear on the inside, I found mine in my tailings when I was gold prospecting, it fooled me because it was tumbled for a while by the creek I found it in. I don't know what yours is it just resembles in a small way of what I found. I'm not sure the hardness of glass but google it try a scratch test, mine is heavy is yours?

Old campfires are likely the source for melted glass

Mine was found out on the high plains of Colorado (range, not farmed,) and far from anything like a ranch. It's pretty angular and doesn't seem like it has been tumbled by a stream, though it is not sharp like obsidian or broken glass. It feels about the same wieght as a regular rock of the same size. Maybe a little lighter. The bubbles are tiny, like a soda pop bubbles, and evenly distributed thoughout the piece. The bubbles that are half on the surface constitute little pits.

I Googled the scratch test. A penny would not scratch it so I used the knife blade on my Leatherman. It would not scratch it either. The only other hard thing I have around here is a thumb tack and it won't scratch it either. I don't know what else to use around here. I did use the thumb tack to dig some dirt out of some of the half-open air bubbles and was able to chip/shatter some of the tiny edges off but I can't scratch it.

Next time I go to town I will stop by a rock shop and ask them what it is. In the mean time, thanks, and I'll take any other ideas.

Glass for sure.

Hi Folks: Finally got to town and to a rock shop. It's glass. Don't know how it got to where I found it, or how it took that shape, but glass it is.
